Scientists reported yesterday that for the first time they have
detected an increase in "biologically relevant" levels of ultraviolet
radiation reaching the ground as a result of the ozone hole over
Antarctica.
This is the first indication that the depletion of ozone, which
blocks much of the sun's ultraviolet radiation, is beginning to cause
the potentially harmful effect that has long been predicted.
Levels of ultraviolet measured on the Antarctic Peninsula during
mid-October, when the seasonal ozone hole is most severe, were found
to be much higher than normal and typical of the higher levels found
in summer, according to Dan Lubin and John E. Frederick of the
University of Chicago ...
